I have had intercourse on the 14th day of my cycle ie: my ovulation day. He ejacualted in me twice once at 9:30 pm on 14th day and once at 9:30am on 15th day and I took I-pill on 15th day of my cycle at 10:30am. Will this avoid pregnancy?

The I-pill is not 100% effective, so there is still a chance of pregnancy. No form of birth control is 100%, so any time you have sex, even with protection, or even if you take the morning after pill, pregnancy is still possible.

Good luck.

The Remedy to Avoid Pregnancy: Do not have intercourse (especially not at the probably perfect time in your cycle to get pregnant).

Now you wait.

Then what is the remedy to it?

The only way to avoid pregnancy completely is to avoid sex. You can get pregnant any time you have sex, especially because you're having unprotected sex.

Now you have to play the waiting game. Abortion is an option if you are pregnant. Hope that you get lucky this time and learn from your mistake.
